Title: Manufacture of one-way material for helicopter
Inventor: MATSUMOTO TADAHIRO
IPC: B29C70/34
Filed: 1989-12-28
Abstract: PURPOSE:To reduce tensile stress in the direction of 90 deg. in manufacture of one-way material for a flex beam or the like by operating a delivery part in such a way that the delivered locus of composite material roving forms a '8'-shaped loop, as well as rotating a mandrel simultaneously, and winding the roving on the mandrel spirally. CONSTITUTION:The delivery member 2 of a filament winding device 1 is operated in such a way that the delivered locus of composite material roving 3 forms an '8'-shaped loop like a locus line L, and simultaneously, a mandrel 4 is rotated in the direction of an arrow mark A. The composite material roving 3 is then wound around among pins 5a-5d. The composite material roving 3 therefore repeats the action of being locked in the order of the pins 5a 5b 5c 5d and is wound around the mandrel spirally. After the specified winding, the composite material roving 3 is pulled out of the mandrel 4. With this constitution, tensile stress in the direction of 90 deg. can be reduced.

Title: Method for dehydrating water solution of organic matter
Inventor: SEIRIYOU FURUTO
IPC: B01D61/36
Filed: 1991-12-26
Abstract: PURPOSE:To make treatment with high dehydration and concentration efficiencies in a method for dehydrating water solution of organic matter where the water solution of organic matter is brought into contact with a pervaporation membrane and vapor permeating through the membrane is condensed and separated by keeping the secondary pressure sufficiently low.

Title: Overcurrent protection apparatus of controller for railway vehicle
Inventor: IDE YUTAKA
IPC: H02M3/135
Filed: 1997-12-15
Abstract: PROBLEM TO BE SOLVED: To perform the protective operation of the controller of an inverter apparatus as sensing the abnormality of the controller, by comparing the output- current command value issued from its controller with its actual output current, and by operating the overcurrent protection circuit of its controller when its actual output current exceeds the command value in some case, and further, by stopping its operation. SOLUTION: For setting an overcurrent-protection setting value to a comparator 14a, an adder 16 adds a marginal portion to an output-current command value 18 issued from an inverter controlling circuit to apply a resultant addition value S8a to one input terminal of the comparator 14a. Then, when the output signal level of an absolute-value circuit 13 exceeds the output signal level S8a of the adder 16, the comparator 14a is configured to output an overcurrent sensing signal S11. When the overcurrent sensing signal S11 is outputted, the inverter controlling circuit stops the outputting of the on-off signal of a witching element, and a gate driving circuit also stops the outputting of the on-off signal (gate pulse) for driving the switching element to stop the power converting operation of an inverter apparatus.

Title: Electromagnetic driving device
Inventor: IKEGAME TETSUO
IPC: H02K41/035
Filed: 1992-12-24
Abstract: PURPOSE:To eliminate the need of a counter balance fitted to the bottom of a driving section so that the driving section can be reduced in size and weight and improved in driving sensitivity by shifting the center of the magnetic surface of a first magnetic member against the center of the magnetic surface of a second magnetic member in the direction perpendicular to the direction of a force generated by a coil. CONSTITUTION:In this driving device in which a disk 3 is held by means of a spindle motor fixed on a base 1 and a mover 4 on the base 1 is moved in the X-direction, the center of a magnet 10 in the Z-direction is made higher by Z2 against the centers of a center yoke 6, side yoke 8, and coil 27 in the Z-direction. As a result, the density center (f) of the magnetic flux crossing the coil 27 in the magnetic gap between the yoke 6 and magnet 10 becomes higher than the center of the yoke 6 in the Z-direction by Z2X1/2. Therefore, the mass of the balancer to be provided below a mobile section 4 to align the centroid of the section 4 with a driving center F can be reduced.
